Title: Liquid cristal cosmetic composition
Inventor: LYLE IAN GARDNER
IPC: A61K8/00
Filed: 1996-09-17
Abstract: A process for reversibly applying a cosmetic composition to the skin or hair comprises: a) contacting the skin or hair with the cosmetic composition, the composition comprising at least one amphiphilic material which is capable of forming a water-insoluble liquid crystal phase of greater than one-dimensional periodicity and a cosmetic agent; and b) when desired, removing the cosmetic composition by applying to the skin or hair a cleansing composition comprising a surface active agent and a hydrotrope capable of destroying the liquid crystal phase formed in step a). An advantage of such a system is that the cosmetic agent is strongly adhered to the skin or hair when applied and can be effectively removed therefrom when desired.

Title: Gob arrival timing in an individual section machine glassware forming system
Inventor: SCHWARTZ STEPHEN M
IPC: C03B7/10
Filed: 1998-04-21
Abstract: In an individual section (IS) machine glassware forming system that includes a gob distributor for delivering glass gobs to individual machine sections in sequence, blank molds at each machine section for forming gobs into blanks and blow molds at each machine section for forming the blanks into hollow glass containers, apparatus for timing arrival of the gobs at each machine section and terminating operation of a section in the event of an imminent gob misload comprises gob sensors and associated electronics for determining gob arrival timing at each machine section. The gob arrival timing so determined is compared to a preset shut-down limit at each machine section. Operation of the blank molds at a machine section is immediately terminated when gob arrival timing at that section exceeds the preset limit, while the blow molds and ware transfer mechanisms for that section are permitted to complete an operating cycle. In this way, damage to the blank molds and generation of tramp glass are prevented while the section is cleared of acceptable glassware.  After the potentially misloaded glass is cleared and any necessary repairs are made, the machine section may be restarted employing normal restart techniques. Operation at the other machine sections continues without interruption.

Title: Method and apparatus for regenerating a moist adsorption medium
Inventor: CRAWFORD ROBERT R
IPC: B01D53/04
Filed: 1998-06-12
Abstract: A method and an apparatus for regenerating a moist adsorption medium in a multiple vessel drying system utilize a pulsed control of a purge gas outlet valve during a regeneration phase. Internal heaters are embedded in the desiccant beds.  During the regeneration phase of a desiccant bed, the internal heater heats the desiccant to remove the moisture therefrom in the form of water vapor. After the water vapor builds up in the drying vessel for a certain period of time, the purge gas outlet valve is opened for a period of time just long enough to flush the built up water vapor from the vessel, and is then closed again. Accordingly, the amount of purge gas required is minimized, which leads to a higher quality purge, higher overall system drying efficiency, as well as reduced energy requirements.

Abstract: The isolation and characterization of a group of odorless and non-volatile glycosides from extracted hops (hop solids which have been previously extracted with non-polar solvents) is disclosed. These glycosides are water soluble and consist of a group of aromatic compounds conjugated to mono-, di-, and trisaccharides. These glycosides are responsible for the formation of kettle hop flavor and taste through both chemical and biological transformations. When these glycosides are transformed, they yield an essence and flavorant which imparts a kettle hop flavor and taste when the essence and flavorant is added to an unhopped beer. These kettle hop flavor essences and flavorants provide economy, consistency, flexibility, quality, and convenience to the brewing process because only one unhopped wort is required to brew a stock of unhopped beer. The unhopped beer can then be dosed with the desired amount of kettle hop flavor essence and flavorant.
